Question

The fraction of water vapor at 300 K and 8 atm is 0.8. Calculate the fraction of water vapor at the same temperature and 1 atm pressure?

(a) 0.1

(b) 0.2

(c) 0.3

(d) 0.4

The question was posed to me during an internship interview.

This interesting question is from Vaporization topic in division Multiphase Equilibrium of Chemical Process Calculation

Answer 1

Correct option is (a) 0.1

To explain: Fraction of water vapor at 300 K and 1 atm pressure is 0.8/8 = 1.
